Microsoft Vision Scope error: System.MissingMethodException

Hi,

I am trying to use Microsoft Vision activities for image recognition, but am getting System.MissingMethodException for all of the Microsoft Vision activities. When I try the same methods using my trial Azure credentials(Endpoint, Key) from a separate Python code, I am getting the correct results. Can anyone please help me out?


Hi @Madmaxf1,

It might be dependency matter of libraries. For now, can you try to downgrade UiPath.UiAutoamtion.Activities package to 21.10.7?

Hi,

Can you check which version is resolved in Azure.CognitiveService.Vision.ComputerVision etc? We can know it from project panel and icon’s color ( or hover on it)

If it’s not 6.0.x, we might need to downgrade other package in order to resolve it as 6.0.x.
